AZGPS FAQ Directory
Land surveying is the science, art, and legal process of measuring and mapping the Earth’s surface to determine property boundaries, land features, and elevations.
Surveyors use advanced instruments like GNSS (Global Navigation Satellite Systems), total stations, and 3D scanners to collect precise geographic data for construction, engineering, and property ownership.
In Arizona, all official boundary or design surveys must be performed or supervised by a Registered Land Surveyor (RLS) licensed by the Arizona State Board of Technical Registration.
📍 1. The Purpose of Land Surveying
Land surveying defines where property boundaries begin and end. It ensures structures, utilities, and improvements are placed accurately and legally on the ground.
Surveying data also forms the foundation for mapping, engineering, and infrastructure development across Arizona.
🧭 2. Common Types of Surveys
Each survey type serves a different purpose:
- Boundary Surveys – Define property lines and corners.
- Topographic Surveys – Map elevation, contours, and site features.
- ALTA/NSPS Surveys – Meet national standards for real estate and title insurance (NSPS Standards).
- Construction Staking – Mark design locations for builders and contractors.
- Subdivision & Platting – Create or modify property parcels per Arizona Administrative Code R4-30.
- FEMA Elevation Certificates – Document elevation data for flood insurance or Letter of Map Amendment (LOMA) requests.
⚙️ 3. Modern Technology in Surveying
Today’s Arizona surveyors use GNSS Network RTK, aerial drones, LiDAR, and 3D modeling software to achieve centimeter-level accuracy.
Learn more about GNSS technology from the National Geodetic Survey (NOAA NGS).
⚖️ 4. Legal and Professional Standards
Surveying work must comply with Arizona’s Administrative Code R4-30-301 through R4-30-312, which define standards of practice, accuracy, and documentation for Registered Land Surveyors.
Survey maps are legal records that may be filed with your County Recorder’s Office.
In Summary
Land surveying establishes the foundation for every property boundary, construction project, and infrastructure plan in Arizona.
A Registered Land Surveyor (RLS) ensures your site data is accurate, legally defensible, and compliant with state requirements.
